Transparent Belgian Church

Built of 100 layers of stacked flat steel plates in the Belgian region of Haspengouw,"Reading Between the Lines" takes the form of a church as its starting iconography. It transforms from solid to nearly transparent depending on the perspective of the viewer. Designed by a pair of young architects in Leuven, Pieterjan Gijs and Arnout Van Vaerenbergh, who collectively go as Gijs Van Vaerenbergh, it is part of a larger exhibition project Z-OUT, an initiative in which Z33, the contemporary
art museum of the city of Hasselt, presents art in public spaces.

Opaque:

The shades of red and brown are from the rust that has accumulated on the unfinished steel structure.

In this closeup from during construction you can see how the layers are stacked. As this is still in the workshop, the fresh grey steel has not yet started to rust.

These photos are from the artists website, there are plenty more there and a video clip of the actual construction.
